i want :
1) starts every day at 1st hour
2)1 day must have 9 hours
3)the others 4 days must have: 8 hours for one day and 7 hours for 3 days

different variants. depending on your dataset.

add students not available from Tuesday to Friday in hour 9.

then you can do different variants:

1) you might already know the activities that should be late (in hour 8 and 9). in that case use activity preferred time constraint for that activities and allow all other only hour 1-7 (by an activity tag)

or

2) add students work in an hourly interval max 2 time from begin of hour 8 to end of hour 8. (2, because for monday and an other day)

[Liviu Lalescu]

Add two students interval max days per week constraints (the maximum allowed such constraints is three for each students subgroup, so it is allowed for you):

a) 9 to end of day, max 1 days.

b) 8 to 9 (or to end of day), max 2 days.

And max 0 gaps per week for all students.

You could try to use other constraints as well: students min 7 hours daily, or activities occupy max time slots from selection.

Maybe:

a2) Students min 7 hours daily and

b2) Students interval 8 to 9 (or to end of day), max 2 days per week.

Please think also yourself and try.
